I have gone with Cloud 9 Tours for a total of 6 years. I have seen what it is like when there are many storms to chase and when there are no storms to chase. Charles and the drivers try very hard to find things for everyone to do when there are no storms to chase. When there is something to chase they will do their best to be on the stomr that has the best chance of producing a tornado. They also answer any questions a tour participant may have about storm chasing. All of the drivers and Charles are very knowledgable about storm development and storm chasing! They like to have fun, but when it is time to be serious they are. They want to see a tornado as much as the participants do. They are concerned about safety. This is a group that I love to go with and highly recommend to anyone interested in storm chasing. Cloud 9 is one of the oldest storm chasing tour groups.
